FEEDING MECHANISM FOR FR INGING MACHINES Filed Dec. 19, 1941 5 Sheets-Sheet 3 ATTORNEY Patented May 23, 1944 or ies FEEDING MECHANISM FUR FRINGING MACHINES Peter Trabulsi, Fairview, N. J. Application December 19, 1941, Serial No. 423,584 2 Claims. (01. 112-64) This invention relates to feeding mechanism i and deals more particularly with means for feeding mufliers or like articles to machines which apply fringe to said mufiiers.

The primary object of the invention is to provide a mechanism whereby a mulfler or like article is presented to a fringing machine and is moved or fed in relation thereto whereby a plurality of tassels in spaced relation are applied to that end of the muffler which i presented to the fringing machine.

Another object of the invention resides in the provision of a machine for feeding mufflers or like articles to a fringing or like machine without the need of continuous observation of a machine Fig. 2 is a sectional elevational View as taken substantially on the plane of the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary detail sectional view of a portion of the mechanism shown in Fig. 2, the parts being illustrated in a different operative relationship.

Fig. l is an elevational view, partly broken, of the feeding mechanism herein disclosed.

Fig. 5 is a detail, partial sectional, partial elevational view of the driving means for the attendant, the operation being automatic except for the initial presentation to the fringing machine of that end of the muffler upon which the fringe is to be applied.

A further object of the invention resides in the provision of feeding means of the indicated type wherein a muffler is fed intermittently and wherein the increment of feed may be changed in accordance with thev number of tassels of fringe to be applied to said mufiler.

A still further object resides in the provision of means for automatically stopping the feed of the feeding mechanism and simultaneously stopping the operation of the fringed machine after the last tassel of a plurality has been applied to a mufiier or like article.

At the present time, fringing machines are fed by hand and require the continual attention of an operator. By means of the present invention,

a plurality of fringing machines may be operated by one attendant who merely presents a muffler or the like to the fringing machine and initiates the feed of each of said plurality of machines as the cycle of operation thereof is accomplished. It is apparent that much saving of time and cost of production is effected and that uniform fringing is obtained.

The structural details of the instant apparatus also form a material part of this invention, the accompanying drawings comprising an embodiment thereof as at present conceived. The following detailed specification which is based on the drawings will more clearly reveal the enumerated and other objects, features and advantages of the invention.

In the drawings:

Fig. 1 is a top plan view, partly broken, of a feeding mechanism constructed in accordance with the invention and shown in relation to portions'of a fringing machine.

feeding mechanism, the view being taken in the direction of the arrow 5 of Fig. 1.

Figs. 6 and 7 are detail sectional views of portions of linkage shown in Fig. 5.

Referring to the drawing in greater detail, the herein contemplated feeding mechanism comprises generally a table it and a carriage l l supported on said table and movable in relation thereto.

The table I0 may be constructed in any desired manner and as here shown is comprised of structural sections fabricated to comprise a rigid support which may rest upon the floor, adjacent to, and preferably in front of a fringing machine. The table it may be provided with guide rail I2 for rollers i3 carried by the carriage l I, said carriage being thus supported for transverse movement with respect to the table Ill.

The carriage I! may be provided with a plurality of transversely disposed bars Hi connecting the side frame portions l5 whereby the carriage is formed as arigid, non-distortable structure. These transverse bars M serve, in the present instance, to support a stack of mufiiers or like articles such as shown at it. said mufflers being placed on the carriage in such a manner as to present one end thereof in such relation to a fringing machine as to properly receive fringe tassels formed by said machine.

In order to hold the stack of mufiiers it against inadvertent displacement, a clamp bar I! may be arranged transversely between the frames [5 and across the width of the stack substantially at the middle thereof. After the stack of mufflers has been placed upon the carriage, all. of said stack, except the lowermost muffler, is folded back, as shown at Ifia in Fig. 4, the lowermost muffler being left in position to be operated upon by the fringing machine. Fig. 4 illustrates how one of the mufflers as at Ifib, is positioned to be operated upon, the remainder of the unoperated upon mufflers remaining folded and those upon which fringe had been applied being dropped down as shown at 160, out of the way ofthe mechanism. It may be seen that as each muffler of a stack is fringed the succeeding one may be positioned for fringing until all of the mufflers of a stack have been fringed at one end. Upon completion of this operation, the entire stack is turned, end for end, to present the other ends of the mufflers for fringing, as above described.

The carriage H is provided with means for clamping the ends of the mufflers to be fringed. For this purpose, a fixed plate I8 is provided to cooperate with a plate l9 carried by arms 20 hinged at 2| to the frames l of the carriage. By grasping the knob 22, and thereby lifting the plate 19, room is afforded to dispose the mufiler end Nib upon the relatively fixed plate l8 in proper relationship to the fringing machine. Release of the knob 22 will permit the plate [9 to engage said muffler end. It becomes evident that the mentioned end l6b of the muffler will move with the carriage H as will be later described.

Means are provided for effecting an intermittent feed of the carriage and thus of the end of the muffler to be operated upon. For this purpose, a shaft 23 of the fringing machine is employed. This shaft which performs one revolution for each tassel forming operation of the machine, is provided with a cam 24, said cam being positioned to engage a bridging yoke 25. Said yoke at each end is provided with a guide clip 25 guided as in brackets 21 carried by the table it. The guide clips 26 are each preferably provided with a roller 28, said rollers serving to support a serrated or toothed feed bar 29 guided in the clips 26.

The carriage I l supports a complementary serrated or toothed bar 30 arranged in operative relation to the bar 29, the bar 3!) being preferably resiliently carried, as by studs 3|, by the carriage side frames l5.

The foregoing is descriptive of means for effecting intermittent engagement of the bars 29 and 30. Means are provided to effect a transmission of the movement of the bar 29 to the bar 30 and thereby effect intermittent movement of the carriage H. The movement of the bar 29 is initiated in an oscillating shaft 32, said shaft being part of the fringing machine and being employed to oscillate the feed bar 33 of said fringing machine.

For the above purpose, the shaft 32 is provided with a preferably arcuately shaped slotted arm 34 connected by a link 35 to an arm 36 on a shaft 31. The latter shaft serves to oscillate a lever 38 which has connection with the feed bar 33 of the fringing machine. It may be seen that the degree of movement of the feed bar 33 may be varied in accordance with the position of the end 39 of the link 35 in the slot of the arm 34.

The shaft 31 may be extended to serve as the means for effecting the mentioned movement of the notched bar 29. However, the arrangement of the machine parts do not permit of such a direct connection and for this reason, the oscillatory motion of the shaft 31 is transmitted to a jack shaft 43 as by means of arms 4| and 42 and a connecting link 43. Upon said jack shaft there is preferably mounted a forked, slotted lever 44 to which one end of the notched bar 29 is connected, as best seen in Figs. 2, 3 and 5.

From the above it may be seen that the oscillation of the shaft 32 serves to both operate the feed bar 33 of the fringing machine and the feed bar 29 of the feeding mechanism, and that any change made in the movement of one commensurately affects the other.

The operation of the above parts is as follows. Starting with the position of Fig. 2, the lever 44 is first swung to the left to the position shown in Fig. 3. The cam 24, under continuous rotation, then presents its high point to raise the yoke 25 and thus raise the drive bar 29 whereby a driving engagement is effected between it and the bar 30 on the carriage. The lever 44 is then moved to the right to effect a movement of the carriage to the right as viewed in Fig. 2, and toward the top as viewed in Fig. 1. As the cam 24 continues its rotation, the bars 29 and 30 separate to leave the carriage in its new position. From this point the cycle continues, the carriage being given an intermittent motion as indicated. During the period of rest of the carriage, the fringing machine operates to apply a tassel to that portion of a muffler which is presented to it as carried by the carriage.

The alternate feed of the muffler and the frin ing thereof continues until such time as the number of tassels desired has been applied. The feeding mechanism then acts to stop the operation of the fringing machine. 'In the present instance, this stoppage is effected by de-clutching the drive of the machine (not shown). A clutch operating lever 45 is provided, said lever having either a clutching or a de-clutching position. In the present instance, it is preferred to arrange said lever to seek a de-clutching position and to latch the same in clutching position. Such latching means may comprise a lever 46 pivoted at 4'! to a bracket 48, the lever 46 being provided with a latch shoulder 49 held in position by a spring 50 to maintain the lever 45 in latched position. The lever 45 may carry an abutment plate 5| which is arranged in the path of movement of a trip finger 52 carried by the carriage l l as by means of support straps 53. As best seen in Fig. 2, it is obvious that as the carriage approaches the end of its movement, the trip finger 52 will engage the abutment plate 5! to tilt the lever 45 against the force of the spring 511 to withdraw the latch shoulder 49 from engagement with the clutch lever 45. The latter is thus freed to move and effect de-clutching of the machine.

If, at any time during the operation of the mechanism, it becomes necessary to stop the operation of the machine, the clutch lever 45 may be released manually by pressing upon a handle 54 of a manual tripping rod 55 to urge an end of said rod against the abutment plate 5| to rock the lever 45 as above described. A spring 56 may be employed to hold the tripping rod 55 retracted until manual operation thereof is desired.

Relatching of the clutch lever 45 and thus institution of the operation of the machine may be effected by manual movement of a lever 51 connected as by the chain 58 to the clutch lever 45. It will be noted particularly from Fig. 1 that both the manual trip lever and the manua1 operation starting lever are both positioned where they are readily accessible to the attendant at the station which he or she must assume to place a muffler in position for fringing.

After a muffler has been completely fringed at one end, and it is desired to start the fringing operation upon the next succeeding one of the stack H), the carriage ll must be returned to its initial position, that is toward the left, as viewed in Fig. 2, and toward the bottom, as viewed in Fig. 1. The carriage may be readily returned to the desired initial position should the bars 29 and 30 be disengaged. Should they be engaged, however, at the end of the cycle of operation, it

becomes necessary to disengage them. For this purpose, a handle 59 is provided, said handle being depressed around its pivot 60 to raise the bar 30 out of contact with the bar 29. In this condition the carriage may be readily rolled back to the desired initial position.

The foregoing is descriptive of a machine for the intended purpose as at present conceived. It is obvious that many changes may be made within the spirit and scope of the invention as claimed. It is, therefore, intended that this disclosure be considered as by way of example only.

What I claim as new and desire to secure by Letters Patent, is:

1. A feeding mechanism of the character described comprising a support, a yoke carried by said support and guided for vertical movement, a driving member engaged by said yoke and reciprocated vertically thereby, said driving member being reciprocable in the direction of feed trans versely of said support, guide rails on the support, a carriage mounted on said guide rails, means on said carriage for supporting a stack of articles to be fed, and a driven member carried by said carriage and arranged for engagement with the mentioned driving member whereby the vertical and transverse movements of said driving member efiect intermittent engagement thereof with the driven member to effect intermittent transverse movement of the carriage with respect to said support.

2. In feeding mechanism of the character described, a support, guide rails on said support, a carriage mounted on said guide rails, a driven member having a serrate longitudinal edge and carried by the carriage, a driving member having a serrated longitudinal edge in cooperative relation with the commensurate edge of the driven member, means for moving said driving member both into driving engagement with the driven member and transversely of the support whereby intermittent movement of the carriage with respect to the support is eifected, vertical guide means on said carriage for said driven member, and manually operable means pivotally supported on said carriage and connected with said driven member for eiTecting manual separation of said driven and driving members.
